Some students routinely copy off others and probably have been doing so their whole lives. The best way to prevent this is to provide each student with a different set of problems, not just the same problems in a different order, but problems with different answers.
The following are PDF files, each containing 25 sets of problems, with the answers on the last page(s).

More Criss Cross Bigger numbers.
